UNTTED STATES PATENT LEVI N. WARREN, OF MILWAUKEE, `WISCONSIN.

Speciiication forming part of Letters Patent No. 55,1S1l, dated May 29., 1866.

To all whom it may concern:

Be it known that I, LEVI N. WARREN, ot' the cit-.y and county of Milwaukee, and State of Wisconsin, have invented a new and useful Improvement on a Grain-Drill; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation ofthe saine, reference being had to the annexed drawings, making a pa-rt of this specification, in which- Figure 1, Letter A, is a perspective view.

Fig. 2, Letter B, is a transverse sectionthrough the grain-box. v

Fig. 3, Letter G, is a transverse section through the grain-box, showing the spur-gearing.

Fig. Ll, Letter D, is a section of the frame or bottom of drill, the falling bar, the lever bar, the detachment-lever, the detachment-rod, the detachment cogwheels, the lever bar. the straps connecting the lever-bar and the falling bar, the pulley over which the straps pass, the sub tube in dotted lines, and the ground-tube.

Fig. 5, Letter E,iuterior of grain-box, showing the agitator, the position ot' the spur-gearing, the inclined-plane aperture-plate, and the regulator or gage which controls the quantity. ot' seed to be distributed.

Fig. G, Letter F, the under side ot' the bottom of the grain-box, showing the sliding plate and its aperture, and the movable gage controlling the sliding plate and the size of aperture and position ofthe gearing.

Fig. 7, Letter G, is the inside view of the cylinderbox, showing the double cylinders and the space for the gearing.

Fig. 8, Letter H, is the bottom frame-work, and showing the axles in two lengths, the falling bar, the straps connecting with the lever-bar, the lever-bar, the rollers over which the straps pass, and the position ot the groundtube. Letter t' is the grain-box; j, the agitator; k, the inclined-plane aperture-plate; l, aperture for grain to the double cylinders; m m, double cylinders 5 a l1L,cylinderbox5 o, tube from cylinder-box directing grain to sub-tube 5 p, sub-tube; q, ground-tube, directing grain from sub-tube into the ground. This ground-tube is attached to the falling bar, and depressible by action of the lever-bar, as desired; l, lever-bar; s, de-

tachment-lever; t, detachment-rod connecting and acting with lever-bar and the falling bar 5 u, straps attached to falling bar and lever-bar 5 o, pulley over which the straps pass; fw, bottom frame; w, the falling bar; y, the axles in two parts xed in the hubs lot' the wheels and revolving 0n journals at the inner ends; z, the boxes for axles and journals on inner ends of axles, allowing for reverse revolutions of the axles and wheels in turning about the graindrill. Letter a No. 1, handle to lever-bar; b 2, sliding plate on the under side of the cylinderbox; c 3, regulating-gage controlling sliding plate and sliding-plate aperture; (l 4, aperture in sliding plate 5 e 5, the cleats forming groove VVfor the sliding plate; f 6, detachment cogwheels, in detachment lever controlled by the action of lever-bar, are thrown in and out ot' gear with other wheels.

The operation of the inclined-plane apertureplate is to facilitate the delivery of the grain. The operation of the falling bar is to operate a series of ground-tubes permanently attached to the falling bar and raised and lowered by one operation.

The operation ot' the lever bar with the straps of leather or equivalent attached to the lever-bar and the falling bar performs the operation ot raising or lowering the ground-tubes and falling bar, as desired.

The axles bisected between the wheels, with their journals on the inner ends, allow for contrary or reaetin g revolutions in turning about the drill, the inner ends of axles revolving in box z.

What l claim,- and desire to secure by Letters Patent, is-

The inclined metallic aperture-plate 7c, or its equivalent, the metallic sub-tube p, with iiexible joint, the attachment of the groundtubes q to the falling bar all in combination.

2. The combination of the detachment rod and lever in elevating the ground -tnbes and detachin g the gearing wheels at one operation, substantially as described and shown, and for the purpose set forth.

. LEVI N. WARREN.
